Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Benzyl-4-[(4-chlorophenyl)sulfanyl]-2-phenylpyrimidine-5-carboxamide.
N-Benzyl-4-[(4-chlorophenyl)sulfanyl]-2-phenylpyrimidine-5-carboxamide (CAS 477859-41-9), molecular formula C24H18ClN3OS and molecular weight 431.94 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, N-Benzyl-4-[(4-chlorophenyl)sulfanyl]-2-phenylpyrimidine-5-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures N-Benzyl-4-[(4-chlorophenyl)sulfanyl]-2-phenylpyrimidine-5-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
